yea, you probably disconnected a hose or wire by accident somewhere. just recheck everything. since you say "while i'm driving" it's obviously running good while it's not trying to idle, so my guess would be you forgot to hook a vacuum hose up somewhere

i just checked it over and looks fine. tightned the plugs a little more and now it idles roughly from 450-1100 RPMs for about 5-6 seconds before stalling. the boots? on the wires were the wires connect to the plugs seem loose. i had to really pull and twist hard to get them off and now i can pull lightly and the pop right off. i know i didnt pull the wires to get them off the plugs.... thanks guys.

found a hose that is as hard as a rock and has some small cracks. i have a 1.9 H0 (88 egt) and its the hose about 2 inches back and about 2 inches down from the PCV valve. its on the right hand side of the engine. its all connected but there seems to be some oil where it connects to the engine so i dont think the seal is completely tight. can anyone tell me what this hose is called so i can go to the store and get it? or is it something a mechanic should replace? thanks

The gap in the plugs widens over time. Yes that little electrical spark actually pushes them apart! Exactly what kind of plugs did you put in?
what gap does the sticker under the hood specify. I'd go with the sticker over a haynes manual. Also, did you try reinstalling the old ones to see if it got better?

Replace all cracked hoses! Air or vacuum leaks are real bad.

you could gap them anywhere between .2 and 1mm but it still wouldn't make the car idle rough then die.. take off the cracked vacuum hose, replace it, and get back to us. (go to the hardware store and buy 6feet of the hose, it comes in real handy)

yes it would tito.... if its gapped too big...it can miss...therefore making rough idle.... if gapped too small...the spark is hotter and can cause the plug to get hot and crack... then it would sound like its out of timing....(running on only however many plugs were still working)

pballer...my thinking is this..... Since u have new plugs.....are they better plugs? some plugs require more current than normal plugs..thats why there are diff plugs for all cars.....so my idea is to double check the plug....then other option is wires... i remember when i was gettin shit for idle i changed my plugs and still had shit idle...changed the wires and problem solved....i suggest you do that too.

ok, for the know it all's its not going to make a big diff if you gap the plugs a little to wide, that is if you have electronic ignition. youre ignition system, will automaticaly adjust to the size of the gap, by sending more voltage to the plugs. the spark does not push the two pieces apart but infact wears the electrode down, making the gap larger. i always set my gap from .035-.040. when i first read your post i thought maybe that you may have cracked a plug wile puting them in, i used to do that all the time. never use auto light in a four cylinder car. 4 cylinder cars produce to much heat for them. the best plugs to use i think are ngk. japanese oh yea , a little rice for ya.
